Not much reference to this unit here. I have just secured a used one. Now working although still getting to grips with reseting the filters. It is capable of up to 4 bands per channel and has the optional eq board (surprise marked 'JBL CD horn'). I will be using in three channel mode for PA use but if any forum members want more info or have more info then this is the place to start. Photo's of the guts on request!

These were expensive new are very complex, not sure if they will cut it for Hi Fi.

If Klark Teknik are not forthcoming on filter building info then I'll be pestering here again.
